How to unlock the JAK Cataclysm in MW3 and Warzone

While many eyes are turned towards Black Ops 6, Call of Duty’s Modern Warfare 3 is still getting weekly updates and challenges, like a new attachment that sounds incredibly fun.

With a name like “Cataclysm,” this newest Aftermarket Part sounds like a behemoth of sorts. And luckily, it is. The Conversion Kit takes an existing weapon and transforms it into something completely new, and hopefully very fun.

Here’s everything there is to know about the latest weapon-changing attachment in MW3 and Warzone, the JAK Cataclysm.

What is the JAK Cataclysm in MW3 and Warzone?

The JAK Cataclysm is an Aftermarket Part and Conversion Kit for the RPK LMG in MW3 and Warzone. It was added in week two of season five in MW3.

“Command the battlefield with this .50 Cal conversion kit for the RPK,” Activision said. “Slow yet powerful with a high-capacity drum mag, this kit is your enemy’s nightmare.”
